Example parset

The LoSiTo parset is a simple text file that defines the steps in a run. Below is an example parset that can be used with the 5 minute measurement set in the losito/examples folder. This parset will apply the first and second order ionospheric effect, station delay effects, the bandpass and the noise step to the simulated visibilities.

You can execute the example simulation via command-line: losito example.parset.

# Add Faraday rotation effects (using TEC values from the [tec] step)

operation = FARADAY

# Add clock delays between stations

operation = CLOCK

# Add delays between polarizations

# Add beam effects (array_factor+element)
